I always thought it was fairy tales and folklore until I grew up and did my own research. i have never seen anything of this nature, but have talked to credible witnesses who had no reason to lie to me. Nearly every culture has a Big Foot creature; Yeti, Windego, Abominable Snowman, etc. I see no reason why these can't be creatures that have survived as distant cousins of prehistoric creatures. However, the sad truth is that you would think we would have more convincing evidence by now; dead body, etc. But, if Big Foots are smart and related to humans, perhaps they bury their dead. The Giant Squid used to be a myth, now we have it on video.
